MPROVBMENT IN REVEESBLE KNOB-LATCHBS.-

'ro ALL' wHoM tr MAY coucnnu:

Be it known ,that I, WALLACE T. MUNGElLof Branford, in the county of New Haven, and State of Connecticut, haveinv'ented a new Improvement in Reversible Latohes; and I do hereby declare the following, when taken in connection with the accompanying drawings, and the letters of reference marked thereon, to he a full, clear, and exact description of thesaine, and which said drawings constitute part of thisl'speccation, and represent, in l c Figure 1,a side view, y

Figure 2 an`opposite side View,`

Figure 3 an Vinterior view, and in Figures 4, 5, and 6, detached parts.`

This invention relates to an improvement in knob-latches, wherebythe latch-holt may he turned tolserve either for a right or left-hand door, and consistsinthe peculiar arrangement, whereby the latch is made so reversible.

Toenable 'others to construct my improvement,` I will proceed to describe the same as illustrated inthe acc'ompanyingdrawings.

A is the case, B the face-plate, .C the latch-holt, and D the lock-bolt, in outward appearance of Acommon construction.' The-latch-holt is formed upon a. spindle, D, around which a. coil-spring, E, is fixed, hearing against the holt-head and against affixed point, F, within the case,sothat`the tendency of the springis to force the bolt from the case. Gr, the-yoke, is arrangeduround the'follower, with ears H H, against which the followery hears in the usual mannerto draw'inthe latch. -The follower is formed in two part-s, veuch part shown in igs.

4 and 5. Iis the hub formed with a shoulder, ?f, so as to set through the'cas'e in the usual manner, as seen .in iig'. 2,'and has an 'opening through it'for the spindle of the knobs.` Across its inner face is formed arslot, J', andat one end of the said slot a shoulder,` m, is for-med,.an'd into this the follower isset. The followerK,`as seen in iig-4, is formed withtwo pins-lc 11,'to operate upon the yoke to turn to the right orleft, to draw in 'the holt in the usualimanner; On the inner surface of theyoke, p'rojectiosL L are formed, corresponding to the slot J in the hub, and upon the outer projection L another projection lrit-corresponds toV thejshonlder min the hub, and through the -follower isformed Anu opening corresponding to the openinginthe h ub', through which the spindle passes, so that' when the two are set together, asin Figure 7, the openings exactly correspond, and the spindle passes freely through, hut when the follower is moved forward in the slot J, .s o that the projection n sets against the shoulder-m, as in fig. 6, then the spindle cannot be inserted; therefore, when placed within the case, and without the spindle, the-yoke is drawn' forward the spring on the .latch-holt to the position denoted in red, and drawing with it `the yoke K,as also denoted in red, this carries the headof the latch-bolt outside the faceplate, as' denotedin red, and in this position the latch-bolt may be turnedto' etherthe right or left, and when so turned to the proper position, force in the latch-bolt, which carries the'yoke hack against th-e follower,- and forces the follower huelgas denoted in fig. 3, also in fig. 7, arid in thatposition the spindle may he inserted in the usual manner, and when so inserted holds'the follower back, so that when the latch-holt is permitted to return, it will he arrestedhy the points H on the yoke coming in contact with the points c onl the follower, and will be there heldin the proper position for use. Thus it is hot necessary to remove or detach any part of the latch, or operate upon' anything but the latch-.bolt itself, which is always in-position to he adjusted at any time `before the'latch-spindle is inserted, and when the latch-spindle is inserted the latch-holt cannot he changed or moved otheri'than in the usual manner.

-Ido not wish-to be understood as broadly claiming a divided hub, as such is not new, nor'do I wish to be' understood as broadly claiming a reversible latch-bolt, assuch are common and well-known; hut' What I do elaim,and desireto secure by LettersPatent, `is v i The combination of lthe follower K, providedv'upon its inner sidewith thel points 7c le for operating'the latch, and with projections L Land n for receiving the hub the said hub I being provided upon one side with av shoulder z', to form a bearing in the plate of the case, and upon the'opposite sido a slot, J, and shoulder m to receive the projections L L and n on the'follower, and the whole constructed and arranged so as to operate the latch-holt in the manner herein setforth` l W.`T. MUVNGER,
